The group marches up the promontory by a wide stone stair. As they reach the top, they are faced by a stone bridge that connects both islands. The bridge seems solid enough and quite old. Some parts are green and mossy, it's evident no one has cared for the state of it in quite some time.
As the group advances, they notice that there are signs of combat along the bridge. They also notice that there are scorch marks all over, often there's a skeleton, or parts of it, black and rotten, in the spot of the scorch mark. Something or someone must have charred them to death. On a closer inspection Taran and Asterion conclude that those are more likely electrocution marks, like if a lightning has struck the poor fella.
All the sudden, the bones start shaking, and assemble in foul undead creatures!
There's eight of them, four set alight as they rise from their charred spots, the others brandish old and rusty weapons.
